Hi
I have a Panasonic microwave (NN-T695SF) which is just about 2 years old. Suddenly yesterday it's start button has stopped functioning. All the other buttons seem to work but the start button. Please help!

You may have a sticky door switch. Try a simple "slamming" of the door, don't over do it, just a little harder than normal. This may help pop the plunger in the switch back up. The switch could have also become loose and moved out of its adjustment.
If this does not help, a technician should save you time and money with this sometimes perplexing problem.
I had this problem. It turned out the connector tabs on the door microwave switches were dirty, the accumulation of about 10 years of greasy gunk. I cleaned the tabs with isopropyl alcohol (I also used sandpaper and a wire brush, but I don't think those mattered). Now it works.
This problem stumped me. The microwave sometimes would not start. Pressing the start button harder, or slamming the door sometimes helped. Eventually, nothing helped. I thought it might be a defective switch panel, but it always responded to a button press with a beep. I thought it might be misadjusted door switches, but adjusting them did not help. I thought it might be a cracked trace on the control board, but careful examination didn't turn up anything. The microswitches tested good with a multimeter. They appeared to engage in proper sequence when I closed the door. It was only when I removed the entire switch assembly and examined the switches without the connecting wires that I noticed the contamination on the connector tabs.
This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel or keypad.
Ovens are designed (like dryers) so they don't run with the door open.
If you or someone you know decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and disassembly information at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

Thanks, atleast I think I know the problem now. If I could open the screws of the outer body then I would have looked inside. However, it looks like I will need to get this to a technician. Thanks a lot.

All button but the start button appear to work. Took it apart, tested the switches, there was continuity on both switchs, so it could be the board, but where do I get a price and availability on such a thing?

Just installed a new magnetron because microwave was not heating food. Now that magnetron is installed the START button does not work?
